Mexico’s federal tax revenue rose by 11% year-on-year in January 2026, according to preliminary data released by the Ministry of Finance (SHCP). The increase, driven primarily by higher collections from income tax (ISR) and value-added tax (IVA), signals improved fiscal management and a potential strengthening of the country’s public finances ahead of a change in government.
The growth in tax receipts outpaced inflation, indicating real gains in fiscal capacity. This performance offers a measure of reassurance for policymakers as the administration prepares to hand over power following the June 2024 elections. With ongoing commitments to public investment and social spending, stronger revenue inflows may give the incoming government more flexibility to maintain programs without resorting to immediate austerity or additional borrowing.

The uptick reflects both improved economic activity and administrative reforms at Mexico’s tax authority, the Servicio de Administración Tributaria (SAT). In recent years, SAT has implemented measures aimed at closing loopholes and enhancing enforcement. These efforts appear to be bearing fruit, at least in the short term, by broadening the effective tax base and increasing compliance.
While the January figures are encouraging, they represent only a single month of data. Analysts caution that sustained revenue growth will depend on broader economic trends and the durability of recent administrative gains. Mexico’s overall tax-to-GDP ratio remains low by international standards, particularly within the Organisation for Economic Co-operation and Development (OECD), limiting long-term fiscal space.
Moreover, Mexico’s reliance on income and consumption taxes makes its revenue stream sensitive to economic cycles. A slowdown in growth or weakening consumer demand could quickly erode recent gains. As such, while January’s performance strengthens the near-term fiscal outlook, questions remain about how resilient this trajectory will be over time.
